First try various arrangements of sockets and extensions. Some torque wrenches simply won't work due to their large heads. I found a cheapo 3/8s drive small headed one at an ACE Hardware that barely got in and worked for two headjobs. It broke during a retorque but they replaced it free (their last one). You can also manipulate the block, via the tranny and motor mounts (loosen, remove, brace, wedge, twist, cuss, etc.). But you're right, that PS head can be testy. Its why many just pull the motor. Good luck, Joel
